HAIR-STRAIGHTENING BRUSH.

Application filed December 6, 1922. Serial No. 665,242.

To all Lv/tom t lmay concern:

Be it known that I, JENNIE M. Pnooron,

a citizen of the United Stat-es, residing at Pittsburgh, in the coun-tyof Allegheny and State of Pennsylvania, have inventedcertain new anduseful improvements in Hair- S'traightening Brushes, of which thefollowing is a specification.

My invention relates to metal hair brushes primarily designed andadapted, when heated, for straightening frizzly, kinky or curly hair,but it will be obvious that the device may be used for any purposeswherein it is found to be applicable.

Important objects of this invention are to provide a metal hair brush ofvthe type and for the purpose stated, in a manner as hereinafter setforth, having inflexible, rigid teeth mounted for universal movementallowing` the teeth to incline in a direction opposite from thedirection that the brush is drawn over the hair thereby preventinginjury to the hair and scalp; which further includes a toothconstruction having an enlarged head adapted for the retention andltransmission of heat tothe teeth; which may be readily taken apart -tofacilitate the cleaning of the brush and the replacement of the teeth,which permits of its use in connection with any kind of hair dressingwithout damage thereto, and which may be heated in any manner withoutdanger from fire or overheating.

Further objects of the invention are to provide a device of thecharacter described which is simple in its construction and ar-vrangement, strong, durable and efficient in its use, sanitary,attractive in appearance, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, which will appear as thedescription proceeds, `the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes, variations andmodifications in the precise embodiment of the invention hereindisclosed "can be made within the scope of what is claimed withoutdeparting from the spirit of the invention.

In the drawing forming a portion of this specification and wherein likenumerals of reference designate corresponding parts throughout theseveral views Figure l is a side viewy of a hair straightening brush inaccordance with this invention.

Figure 2 is a similar view with portions thereof shown in cross section.

Figure 8 is a top plan view of the device.

Referring in detail to the drawing l denotes the body portion of thebrush consisting of the top member 2 and the bottom plate 3. rlhe bottomplate 3 is positioned ljlatly against the under face of the top mem- Thebody portion l is preferably elongated and rectangular in contour and isformed at its rear end with a tapering' neck 4. A handle support 5 isintegrally formed with the neck portion of the top member 2, and extendsrearwardly in alignment relatively to body portion 1. The forward end ofthe handle support 5 overlaps the rear edge of the neck portion of theplate 3. as clearly shown and indicated at 6, in Figure 2 of thedrawing.

The plate 3 is secured at its forward end to the top member 2 by meansof the screws 7, which extend through the perforations provided thereforin the plate 3 and engage in the threaded apertures formed in the underface of the top member 2at its forward end. The rear end of the plate 3is secured against the top member 2 by the engagement of the taperingneck 5 of the body portion l with the contracted forward end 8 of thecoil wireV handle 9, which latter is mounted on the handle support 5and. secured thereon by the screw 10 in threaded engagement in the rearend of the handle support 5 when in position on the support 5. The coilWire handle exerts a spring pressure against its contracted forward/end8 which latter in .turn secures the plate 3 against the top member 2 bythe engagement of their neckportions therewith.

The adjoining faces: of the top member 2 and the plate 3 are eachAformed with a plu.- rality of recesses, each of the recesses `of theplate 3 registers with a corresponding recess formed in the top member 2and forml in combinationl with each other a round socket ll in which theround heads l2 of the teeth 13 are mounted. Each of the recesses formedin the plate 3 is provided with an aperture 12 to permit of theprojection of a tooth 13 therethrough. The apertures 14 are of a.greater diameter than the diameter of the teeth 13, `thereby allowinguniversal movement of the teeth 13 on the well known ball and socketprinciple. The universal movement of the teeth 13 however is limited andcontrolled by the peripheries of the apertures 1li.

rlhe teeth 13 are inserted through t-he apertures 14 of the plate 3before the latter is attached to the top member 2, and are preferablyformed with rounded free ends so as not to injure the scalp of the user.

rJ'he device as shown in the drawing illustrates the teeth 13 arrangedin three longitudinal rows, the teeth of each row being staggeredrelatively to the teeth of an adjacent row.

lt will be obvious that the configuration of the body portion 1, thearrangement of the teeth therein, and the length and contour of thelatter may be varied to best meet conditions found in practice.

ln practice the body portion 1 of the brush is heated by positioning thetop member 2 in direct contact with a heating element. Such heatingelement may consist of an electric or gas heating unit embodied in thetop member itself, oroviding a constant heat, or of aI separate heateron which the top of the body port-ion is temporarily positioned untilproperly heated, and requiring reheating to. maintain the brush at asuitable operating temperature. The top member 2 is constructed ofcomparatively thick metal and will therefore absorb and retain a largeamount of heat. The heads 12 of the teeth 13 being large and in contactwith the '.top member 2 a certain amount of heat will be absorbed andmaintained by the heads 2 and transmitted from the latter to the teethat the proper operating temperature.

T he brush may be readily taken apart for cleaning or for any otherpurpose by removing the handle 9 and screws 7 thereby releasing` theplate 3 from the top member 2 and permitting of the removal of the teeth13.

Fronr the foregoing description taken in connection with theaccompanying drawing, the advantages of the construction and the methodof operation will be readily apparent to those skilled in that art towhich the invention appertains and while describing` the principle ofoperation of the invention together with the device which is nowconsidered to be the best embodiment thereof, it is to. be understoodthat the device shown is merely illustrative and that various changes inthe form, proportion and the minor details of construction may beresorted to without departing from the principle or sacrificing any ofthe advantages of the invention as defined in the appended claims.
